Problems solved by technology

So far, there are very few studies on 2-amino-3-methylhexanoic acid. Except for the 3 patents we have applied for, the rest of the research has focused on bacterial mutants or recombinantly engineered bacteria (non-natural microorganisms) that synthesize the substance. In terms of synthetic pathways and direct inhibition of bacterial activity, there are no related studies, reports and patents involving plant growth regulators, which is where the innovation of this patent lies

Embodiment 1

[0033] Embodiment 1: The influence of 2-amino-3-methylhexanoic acid soaking on the growth of rice seedlings

[0034]Rinse the rice seeds (the variety is "Dengliangyou 2108") with distilled water, disinfect with 75% alcohol for 3 minutes, wash with distilled water for 3 times, and then use NaClO (5%) to disinfect the rice seeds for about 10 minutes. Rinse well with distilled water, and then use a clean filter paper to absorb the remaining water on the surface of the seeds until the surface is dry. Select 50g (grams) of healthy, plump and uniform seeds and place them in a 100mL (milliliter) Erlenmeyer flask. Add 50 mL of 2-amino-3-methylhexanoic acid aqueous solution with a concentration of 0, 10, 100 and 1000 nM to each bottle, take it out after soaking at room temperature for 5 days, select 100 rice seeds with the same germination state, and sow them evenly on the In the rice seedling tray, cover it with sterile nutrient soil, place the seedling tray in a 28°C cultivation roo...

Embodiment 2

[0043] Example 2: Effect of 2-amino-3-methylhexanoic acid on rooting of cucumber seedlings

[0044] In order to further study the promotion effect of 2-amino-3-methylhexanoic acid on the growth of plant roots, a model system for studying root development—the radicleless cucumber seedling system was selected. Spread four layers of wet gauze on the bottom of the seedling box, select cucumber seeds with healthy shape and uniform size (the variety is "Chuxia Qiuguan", Shandong Ningyang County Luming Seed Co., Ltd.), rinse them with distilled water and spread them evenly On top of the gauze, cover with four layers of moistened gauze to protect from light. After being protected from light for 24 hours in a 25°C culture room, take out the germinated cucumber seeds and bury them 1cm below the soil. After 3 days, take some plants with the same growth and two cotyledons fully stretched out. Rinse the roots with distilled water and cut them. Remove the radicle, fix the plant with a spon...

Embodiment 3

[0048] Example 3: Effects of 2-amino-3-methylhexanoic acid stem and leaf treatment on the growth of strawberry, tomato and pepper seedlings

[0049] In 2021, the experiment will be carried out at Changshan Xiangmingyang Family Farm (standard greenhouse nursery base) in Zhangjiagang City, Jiangsu Province. The strawberry variety for testing is Hongyan, the tomato variety is Qianxi, and the pepper variety is Sujiao No. 5. Dissolve 2-amino-3-methylhexanoic acid in distilled water and dilute it with distilled water to 100nM, i.e. 14.5μg / L (microgram / liter) solution, set up a blank control, and add 0.02% Tween 20 as a surfactant at the same time and 14-hydroxybrassinosterol (Sichuan Xinchaoyang Company) with a concentration of 37.5 μg / L were used as control agents. Each treatment was repeated three times, and the area of ​​the plot was 20m 2 , the spray volume of each cell is 1L. The method of processing is foliage spraying, investigates on the 9th day after the application, the ...

Abstract

The invention discloses an application of 2-amino-3-methylhexanoic acid in promoting plant growth and increasing yield, and concretely discloses application of 2-amino-3-methylhexanoic acid in promoting growth of plant seedlings and / or promoting growth of mature plants and increasing yield. The 2-amino-3-methylhexanoic acid is a natural product, has a simple structure and is easy for industrial production. As the 2-amino-3-methylhexanoic acid is confirmed to be capable of promoting plant growth, the 2-amino-3-methylhexanoic acid has the potential of being developed into a natural plant growth regulator. The 2-amino-3-methylhexanoic acid is the natural product, is low in dosage and environment-friendly, and has a remarkable promoting effect on plant growth, so that the 2-amino-3-methylhexanoic acid is a green and efficient biological source plant growth regulator, and the utilization value and the application prospect of the substance in agricultural production are indicated.

Description

technical field [0001] The invention belongs to the field of agricultural biological pesticides and relates to the application of 2-amino-3-methylhexanoic acid in promoting plant growth and increasing production. Background technique [0002] The growth and development of plants not only require the supply of resources such as light, water, and nutrients, but are also regulated by growth substances. Plant growth substances mainly include plant hormones and growth regulators. Plant growth regulators refer to artificially synthesized or extracted compounds with natural plant hormone physiological activities, which can be used to regulate or control certain processes of plant growth and development, such as cell division and elongation, tissue and organ differentiation, seed dormancy and germination, Flowering and fruiting, maturity and aging, etc., to promote or inhibit seed germination, plant growth, fruit ripening, flower preservation or fruit thinning, improve plant immuni...
